Description

"Schaltungsanordnung zur Verringerung von Restwelligkeiten von Gleichstromspeisungenn B'ranzösische Prioritäten vom 2.Oktober 1967 aus der französischen Patentanmeldung Nre 2770 (Belfort) und vom 15.Mai 1968 aus der französischen Patentmeldung Nr. 151 957 (Belfort) Die Erfindung betrifft eine Schaltungsanordnung zur Verringerung von Restwelligkeiten und Reststörungen von Gleichstromspeisungen. "Circuit arrangement for reducing residual ripples in direct current feeds French priorities of October 2nd, 1967 from the French patent application Nre 2770 (Belfort) and of May 15, 1968 from French patent application No. 151 957 (Belfort) The invention relates to a circuit arrangement for reducing Residual ripples and residual interference from direct current supplies.

Bei Speisevorrichtungen, die dazu bestimmt sind, Gleichströme zu erzeugen, wird die elektrische energie im allgemeinen durch eine Quelle geliefert, die eine sich drehende Maschine, ein elektrisches Netz oder deren Kombination sein kann0 Wenn die Spannung an den Klemmen der Quelle eine Wechselspannung ist, richtet man sie gleiche Die nach der Gleichrichtung erhaltene Gleichspannung weist im allgemeinen eine Welligkeit auf. Selbst wenn die Quelle unmittelbar eine Gleichspannung liefert besitzt diese sehr häufig Welligkeiten. In the case of supply devices that are intended to supply direct currents generate, the electrical energy is generally supplied by a source, be a rotating machine, an electrical network, or a combination thereof can0 If the voltage at the terminals of the source is an alternating voltage, directs if they are equal The DC voltage obtained after rectification generally has a ripple on. Even if the source supplies a direct voltage this very often has ripples.

Es ist daher vor der Verwendung einer Gleichspannung meistens nötig, daraus die Welligkeits- und Störspannungen zu entfernen, d.h. die Gleichspannung zu glätten. Diese Glättung dient dazu, sowohl die zyklischen oder sich wiederholenden dem Betrieb der Quelle anhaftenden Welligkeiten als auch die zufällig auftretenden oder sich nicht wiederholenden, die auf die Quelle oder auf Störungen zurückzuführen sind, zu beseitigenO Die Glättung einer Gleichspannung ist umso schwieriger, je größer die Stromstärke, die die Speisevorrichtung liefern soll, und je geringer die Restwelligkeit ist Der Erfindung liegt die Aufgabe zugrunde, eine Schaltungsanordnung der eingangs genannten Art zu schaffen, die auf einfache Weise eine wirksame Glättung von Restwelligkeiten und Störungen ermöglicht0 Diese Aufgabe ist bei der hier vorgeschlagenen Schaltungsanordnung vor allem dadurch gelöst, daß erfindungsgemäß in Serie mit der Gleichstromquelle ein diedereingabeelement angeordnet ist, an dessen Klemmen eine Detektorschaltung, die an ihrem eingang ein von den Anschlußklemmen der Gleichstromquelle oder denen der Last abgenomrnenes Bild der 's'lelligkeits- und Störspannunger. emp-fängt, eine die '2Telligkeits- und Störspannungen an den Anschlüssen der Gleichstromquelle und der Last schwächende Spannung eingibt. It is therefore usually necessary before using a DC voltage, remove the ripple and interference voltages from this, i.e. the direct voltage to smooth. These Smoothing is used to do both the cyclic or repetitive ripples inherent in the operation of the source as well as the random or non-repetitive, referring to the source or on Disturbances are to be eliminated O The smoothing of a direct voltage is all the more difficult, the greater the current that the feed device deliver should, and the lower the residual ripple The invention is based on the object to create a circuit arrangement of the type mentioned, which is simple Way enables an effective smoothing of residual ripples and disturbances0 This In the circuit arrangement proposed here, the task is above all achieved in that that according to the invention, in series with the direct current source, one input element is arranged, at the terminals of a detector circuit, which at its input a disconnected from the terminals of the DC power source or those of the load Image of the brightness and interference voltages. receives, one of the '2working and debilitating interference voltages at the connections of the direct current source and the load Voltage inputs.

weitere Merkmale und durch sie erzielte Vorteile gehen aus der Beschreibung der Zeichnung hervor, in der beispielsweise gewählte Ausführungsformen in die Erfindung erläuternden Blockschalt'bildern dargestellt sind, Es zeigen: Figo 1 eine erfindungsgemäße Schaltungsanordnung in allgemeiner Form, Fig0 2 und 9 zwei speziellere Ausführungsformen der erfindungsgemäßen Schaltungsanordnung. further features and advantages achieved by them can be found in the description the drawing shows in the example selected embodiments in the invention explanatory block diagrams are shown, FIG. 1 shows an inventive Circuit arrangement in general form, Fig0 2 and 9 two more specific embodiments the circuit arrangement according to the invention.

In der in ligo 1 dargestellten Schaltungsanordnung speist eine Gleichspannungsquelle 1 eine Last 2o Ein als Wiedereingabeelement 3 zu bezeichnendes Organ liegt mit der Gleichstromquelle 1 in Serie, Ein an den Klemmen der Gleichstromquelle 1 abgenommenes bild der Welligkeits- und Störspannungen liegt an dem Eingang einer Detektorschaltung 4, die eine Informationsspannung liefert, welche in einer Verarbeitungsschaltung 5 verarbeitet wird und dann an dem Eingang eines Phasenumkehrers 6 anliegt. Die von dem Shasenumkehrer 6 abgegebene Spannung wird an den Klemmen des Wiedereingabeelementes 3 wieder in den Stromkreis eingeführtO Die Übertragungsfunktion der Verarbeitungsschaltung 5 wird entsprechend den Ergebnissen bestimmt, die man an den Klemmen der Last 2 zu erhalten wünscht, Insbesondere kann man, wenn man mit F die tbertragungsfunktion der Verarbeitungeschaltung 5 und mit p den Laplace-Operator bezeichnet, die Funktion: P( p) =1 vorsehen, Die Funktion F(p) kann so die Übertragungslunktion des Wieder eingabeelementes 3 berücksichtigen0 Die Übertragungsfunktion der Detektorschaltung 4 wird in Abhängigkeit von der oder den zu cachenden Frequenzen bestimmt. Insbesondere ist es möglich, ein einfaches Differenzierglied, wie dies in Fig. 2 dargestellt ist, zu verwendens In Fig. 3 ist der besondere Fall dargestellt, bei dem eines der Elemente des Differenziergliedes einen unendlichen Wert hat. In the circuit arrangement shown in ligo 1, a DC voltage source feeds 1 a load 2o an organ to be designated as re-input element 3 lies with the DC power source 1 in series, one on the terminals of the DC power source 1 image taken of the ripple and interference voltages is at the input of a Detector circuit 4, which supplies an information voltage, which in a processing circuit 5 is processed and then applied to the input of a phase inverter 6. the The voltage output by the phase inverter 6 is applied to the terminals of the re-input element 3 reintroduced into the circuit O The transfer function of the processing circuit 5 is determined according to the results obtained on the terminals of load 2 wishes to obtain, in particular, one can, if one uses F to determine the transfer function of the processing circuit 5 and denoted by p the Laplace operator, the function: P (p) = 1, the function F (p) can thus be the transfer function of the re input element 3 take into account the transfer function of the detector circuit 4 is determined as a function of the frequency or frequencies to be cached. In particular it is possible to use a simple differentiator, as shown in FIG is to be used In Fig. 3, the special case is shown in which one of the Elements of the differentiator has an infinite value.

Die Die erfindungsgemäße Schaltungsanordnung kann zusammen mit anderen Abschwächungsvorrichtungen verwendet werden, die in Serie mit der Last geschaltet sind und in die an den Schaltungsklemmen der Last eine Spannung eingefügt wird, die vor der erfindungsgemäßen Schaltungsanordnung abgenommen und passend bearbeitet wurde, The circuit arrangement according to the invention can be used together with others Attenuators are used which are connected in series with the load and into which a voltage is inserted at the circuit terminals of the load, which were removed before the circuit arrangement according to the invention and processed to match became,
